Subject:   fxp0: device timeout with PAE enabled
Message-ID:  <20031019053506.GA55011@dns.in2home.org>

Hi,
We use IBM Netfinity 6000R with 6GB ram to run a large BBS in Taiwan.
everything works perfectly above 4.9-RC without PAE,
but after enabling PAE, something wrong with networking.

with intel 82558B, 82559, 82550, and 82551QM (using fxp driver)
we always get the following error messages:
	fxp0: device timeout         
	fxp0: DMA timeout
and it's not working.

with onboard pcn0 (AMD PCnet/PCI 10/100BaseTX),
we get a lot of packet loss (20% ~ 70%) without any error message.

Realtek 8139 is not working without any error message.

xl with PAE will cause kernel panic when booting:
   Fatal trap 12: page fault while in kernel mode
   mp_lock = 00000002; cpuid = 0; lapic.id = 03000000
   fault virtual address   = 0x10                    
   fault code              = supervisor read, page not present
   instruction pointer     = 0x8:0xa0192429                   
   stack pointer           = 0x10:0xa0395e10
   frame pointer           = 0x10:0xa0395e20
   code segment            = base 0x0, limit 0xfffff, type 0x1b
                           = DPL 0, pres 1, def32 1, gran 1    
   processor eflags        = interrupt enabled, resume, IOPL = 0
   current process         = 0 (swapper)                        
   interrupt mask          = net tty bio cam  <- SMP: XXX
   trap number             = 12                          
   panic: page fault           
   mp_lock = 00000002; cpuid = 0; lapic.id = 03000000
   Uptime: 0s                                        

for testing, we use this program:
   1.install the card and cable,
   2.use the kernel with the driver (only) without PAE and test,
   3.reboot with the kernel only add 'options PAE'
     and increase KVA_PAGES from 288 to 768 and test
at step 2, it works perfectly,
so it should not be bad cable or ...

now we use em0, but there's a lot of packet loss even without PAE :(

is there any suggestion? ^^?
Thanks for your help ^^
